Tavy works well and does not permanently destroy the forest as long as field sizes are small and farmers leave adequate time for re-growth. However, if farmers return to the fallow fields too quickly, as they do when human population densities increase, the soils become exhausted. And if little forest is left in between fields, then there are no parent trees to provide seeds and seedlings to restore the forest. Eventually large areas of forest are transformed into wastelands, upon which nothing can grow—neither rice nor forest. On these areas, farmers pasture a few cattle and continue to burn the grasslands each year, to provide "greener grass" for the cattle.
Answer:
The paragraph illustrated in the question reminds me the first law of thermodynamics.
Explanation:
According to the first law of thermodynamics or law of energy conservation theory states that the total amount of energy of the universe always remains constant.Energy can neither be synthesized nor destroyed.Energy can only be transformed.
Both photosynthesis and cellular respiration obey the law of energy conservation or the first law of thermodynamics.Because during photosynthesis the light energy is converted to chemical energy that is stored in the chemical bonds present in glucose.
Whereas during cellular respiration the glucose is broken down by oxidation to release free energy in form of ATP.
Cancer cells do not respond to signals that regulate the cell cycle , I believe it’s b
Answer:The surface water is easier to get to.
Explanation:
The answer is a “gene”
A gene is a functional segment of DNA that provides the genetic information necessary to build a protein. Each particular gene provides the code necessary to construct a particular protein.
hope this helps !
